Provisioning of Compression and Secure Management Services for Healthcare Data in Cloud Computing

Cloud computing is the use of computing resources that are delivered as a service over a network. Cloud computing entrusts remote services with a users data, software and computation. Cloud computing encompasses three main concepts pay-as-you-go, on-demand and on the Net. Several studies show that the lack of access to resources and shared data is one of the main causes of errors in the healthcare sector. Therefore in this work we propose a novel cloud based image compression technique using digital watermarking which enables embedding one image behind another. We also show that patients information can also be stored along with the image without annotation which helps preserving the quality of the image. We further compare the proposed techniques performance for both medical and non medical images and prove that the method is more suitable for medical images due to gray scale nature of the image data.
